The Importance of Fitness and Bodybuilding

It Can Reduce Your Risk of Chronic Disease

Lack of regular physical activity is a primary cause of chronic disease.

Regular exercise has been shown to improve insulin sensitivity, cardiovascular fitness and body composition, yet decrease blood pressure and blood fat levels.

In contrast, a lack of regular exercise — even in the short term — can lead to significant increases in belly fat, which increases the risk of type 2 diabetes, heart disease and early death.

Therefore, daily physical activity is recommended to reduce belly fat and decrease the risk of developing these diseases.

It Can Help Skin Health

Your skin can be affected by the amount of oxidative stress in your body.

Oxidative stress occurs when the body's antioxidant defenses cannot completely repair the damage that free radicals cause to cells. This can damage their internal structures and deteriorate your skin.

Even though intense and exhaustive physical activity can contribute to oxidative damage, regular moderate exercise can increase your body's production of natural antioxidants, which help protect cells.

In the same way, exercise can stimulate blood flow and induce skin cell adaptations that can help delay the appearance of skin aging.

It Can Help Your Brain Health and Memory

Exercise can improve brain function and protect memory and thinking skills.

To begin with, it increases your heart rate, which promotes the flow of blood and oxygen to your brain.

It can also stimulate the production of hormones that can enhance the growth of brain cells.

Moreover, the ability of exercise to prevent chronic disease can translate into benefits for your brain, since its function can be affected by these diseases.

Regular physical activity is especially important in older adults since aging — combined with oxidative stress and inflammation — promotes changes in brain structure and function.

Exercise has been shown to cause the hippocampus, a part of the brain that's vital for memory and learning, to grow in size. This serves to increase mental function in older adults.

Lastly, exercise has been shown to reduce changes in the brain that can cause Alzheimer's disease and schizophrenia.
